Unless the panel could also generate it's own heat to keep snow off of it this would never work in the northern climates. As paralyzed mentioned the road salt would be an issue but what about a plow scraping it's steel blade across it.

It's an interesting concept but one I think is pointless. Also as already pointed out rooftops, would be a far better application for solar panels, it's already being done but the cost is still to great to be used 99% of the time.
